ated with simple clamping means for clamping the adjustable jaw in opening engagement with the jar top.
A still further object of the invention is to provide a unitary device including cooperating clamping jaws, one of which is fixed and the other is movable for gripping a screw-top jar for opening the same, coupled with means for prying up pry-off caps, and bottle opening means all actuated by the same lever bar.
A still further object of the invention is to provide an opener of the above-indicated character having a fixed jaw member and a pivotally mounted jaw member having mounting means which permits the locking of the pivotally mount- 7 ed jaw in clamping position in engagement with a top to be opened that is held against the fixed jaw member, the mounting means for the pivotally mounted jaw enabling the jaw to pivot freely at alltimes on the mounting means for enabling self-positioning of the jaw against the top to be removed.
A still further object of the invention is to provide an opener of the above-indicated character wherein the pivotally mounted jaw is provided with top engaging surfaces adapted to center the pivotally mounted jaw responsive to the clamping engagement thereof with a top to be opened.
A still further object of this invention is to provide a jar-toppremover, having a fixed jaw member and a pivotally mounted jaw member means which will secure the pivotally mounted jaw member in proper relation with the fixed jaw member when the jaws are moved into operative relation with a jar top, the said means including a stud with a locking bolt therein, and lever means integral with the bolt for shifting the stud between locking and adjusting positions.
A still further object of the invention is to provide a wrench-like screw-top remover for removing tops from jars or the like, having opposed jaws which will automatically adjust themselves to tops of different diameters when placed in engagement therewith, together with means for locking the jaws in adjusted clamping engagement with the top.
Further objects of the invention will become apparent as the description proceeds, and the features of novelty will be pointed out in particularity in the appended claims. 1
The invention will be understood more readily ,by reference to the accompanying drawings, in
which Fig. 1 is a perspective view of the device, showing itinoperative position for opening a screwtop container.
Fig. 2 is a plan view of the bottom side of the device.
Fig. 3 is a side elevation of the device.
Fig. 4 is a plan view of the locking means embodied in the construction.
Fig. 5 is an enlarged sectional elevation showing the locking means of Fig. 4 mounted in position in the device of the invention, the View show- 1 in the actuating means; for the locking means and the mounting thereof on the locking means;
Referring more particularly to the drawings, I
the device of this invention includes an elongated lever bar I and which is provided with a slot 2 extending along the median line of the bar as i shown. One end of bar I is provided on its underside with a fixed jaw 3 having gripping teeth 4 thereon, which project inwardly to grip the screw-top A of a jar, container, or the like, a
movablejaw 5 co-operating with this jaw 3 to grip the screw top (indicated at A) between itself and thefixed jaw 3. In order to grip the top A the jaw 5 includes diverging sides 6 and l, which diverge from the mounting 8, as will be apparent fromthe drawings, said sides 6 and l terminate inserratedarcuate gripping surfaces 9 and ID,
that are adapted to grip the top A therebetween.
The mounting means 8 for the jaw 5 includes a stud ii that has a narrowedend portion I2 stud H. The-narrow end portion I2 defines opposite shoulders I3 and M with the body of the stud II, and forms a neck for receiving the bar l. The opposite end of the stud ll is enlarged with a collar or flange 15, which retains the jaw 5 in place on the mounting means. The stud H is provided with a longitudinally extending axial, internally threaded bore 16 adapted to receive a bolt ll, which is provided with a head 18 and threads IS. The bolt head 18 is provided with a lever arm 29 for turning the bolt, so that when V invention.
the jaw has been moved along the slot 2 into clamping position with the screw top against the bar I, turning of the lever arm 20 draws shoulders l3 and I4 and bolt head l8 into clamping engagement with the bar or handle I and anchoring 5 the mounting 8 in jar top gripping position with respect to the bar or handle I against displacement during the movement of said bar or handlein top removing direction. The jaw 5 thus is locked in position, against the. screwto p, A on o the bar I', thefjaw-5 however beinglfreelji movable witli' respect to the stud ll to per'mi't its self-adjustment with respect to the screw top A due to the configuration of the grippingsurfacesf of the jaw 5. The bar I is recessed as shown at 21, the cut, out portion being bent down to form the flange- 22 which provides means for pryingiofi 'lift-tops -i that are clamped onto a container. The, bar L is also notched as at 23 adjacent to its end'oppo site to the fixed jaw 3 toprovide bottle-cap removingtmeansl Thus 'there is provided fern-3:11 1 purpose opening tool for ffopening anytype ofclosure for containers whether said cl'osures be screw-tops,bottle tops or clamped coversjth'-bar 25 I serving "as the actuating lever'for-each purposel From the above it will be apparent that I have designed a jar or container top opening device; comprising few. parts, T readily I applicable to and easily operable, simple and sturdy in c ')nst'rut tion, manufacturable at a negligible cost, and e111;
